This accommodation rack 80 only accommodates frames 29 and includes no driving source such as a driving section for moving frame 29 and a driving section for lifting and lowering frame 29. With this accommodation rack 80, the configuration can be simplified more. Shelf section 81 has a size which can deal with frame sizes for various types of printing related members. That is, shelf section 81 is sized so as to accommodate largest frame 29. This accommodation rack 80 may be configured to have shelf sections 81 which individually deal with frame sizes for various types of printing related members, or one accommodation rack 80 may be configured to have multiple shelf sections 81 of the same size. In the latter case, multiple accommodation racks 80 having the same external size may be prepared, so that shelf sections 81 of each accommodation rack 80 correspond to any one of frame sizes for various types of printing related members. In this case, although the number of types of accommodation racks 80 is increased, even though frame sizes of corresponding printing related members differ, since the external sizes of accommodation racks 80 are the same, those accommodation racks 80 can individually share receiving section 42. Handle 83 is fixed to an upper portion of rack main body 80a. Handle 83 includes a rod-shaped body configured to be gripped by operator W and a support member which fixes the rod-shaped body.

Receiving section 42 receives accommodation rack 80 having multiple shelf sections 81 where to accommodate frame 29 for supporting a printing related member for use in printing device 11 and supports this accommodation rack 80 from a lower surface side thereof so as to lift up and lower the accommodation rack 80. Rack moving section 43 lifts and lowers, and moves forwards and backwards accommodation rack 80 among an exchange position where to exchange printing related members, a liftable position which lies below this exchange position, and an accommodation position where to enable accommodation rack 80 to enter an interior portion of the housing of printing device 11. As shown in Fig. 3, rack moving section 43 includes lifting and lowering member 44, lifting and lowering drive section 45, hook portion 47, and forward-backward drive section 48. Lifting and lowering member 44 is a plate-shaped member which is provided on a surface of left-hand side unit 41 which faces right-hand side unit 51. This lifting and lowering member 44 is caused to move up and down along an internal surface of the housing of left-hand side unit 41 by lifting and lowering drive section 45. Cam followers 44a are disposed individually at front and rear end portions of lifting and lowering member 44. Cam followers 44a support supporting and fixing member 85 disposed on accommodation rack 80 from below and move accommodation rack 80 up and down as lifting and lowering member 44 moves up and down. Lifting and lowering drive section 45 may have a ball screw having a lifting and lowering shaft and a drive motor so as to move lifting and lowering member 44 up and down or may be configured to move lifting and lowering member 44 up and down using a linear motor. In addition, rack moving section 43 has fixing section 50 configured to, when accommodation rack 80 moves to the liftable position to enter a state in which accommodation rack 80 can be lifted up and lowered, restrict accommodation rack 80 from moving in a horizontal direction and/or from falling. When accommodation rack 80 is lifted up or lowered by rack moving section 43, fixing section 50 functions as a safety mechanism for preventing accommodation rack 80 from moving or falling unintentionally. Fixing section 50 includes a clamp section having clamp lever 52 configured to be inserted in lock hole 88 formed in supporting and fixing member 85, a stopper section having insertion pin 53 configured to be inserted in insertion hole 89 formed in supporting and fixing member 85, and the like.

Forward-backward drive section 48 moves hook portion 47 between an accommodation position and a liftable position. Forward-backward drive section 48 may have a ball screw and a drive motor so as to move hook portion 47 forwards and backwards or may be configured to move hook portion 47 forwards and backwards using a linear motor.
Exchange unit 40 has exchange control section 59. Exchange control section 59 is configured as a microprocessor which mainly includes CPU and controls the whole of exchange unit 40. Exchange control section 59 outputs a signal to printing control section 20 in addition to lifting and lowering drive section 45 and forward-backward drive section 48. In addition, exchange control section 59 receives a signal from printing control section 20 as an input therefrom. When acquiring a signal indicating that accommodation rack 80 is received by receiving section 42, this exchange control section 59 executes a process of lifting up hook portion 47 so as to bring this hook portion 47 into engagement with block section 86. In addition, when exchanging printing related members, exchange control section 59 executes a process of causing rack moving section 43 to lift up accommodation rack 80 from the accommodation position to the exchange position by way of the liftable position. In addition, when the exchange of printing related member is completed, exchange control section 59 causes rack moving section 43 to move accommodation rack 80 from the exchange position to the accommodation position by way of the liftable position.

Subsequently, a printing process which is executed by printing device 11 configured in the way described heretofore will be described. When printing device 11 executes a printing process, automatic conveyance vehicle 16 conveys accommodation rack 80 to exchange unit 40 (a first step in Fig. 6) so as to attach the accommodation rack 80 to exchange unit 40 (a second step in Fig. 6). After automatic conveyance vehicle 16 causes exchange unit 40 to receive accommodation rack 80, operator W inputs a command to execute a printing process from operation panel 38. A printing process routine for execution of a printing process is stored in the storage section of printing control section 20 and is executed after printing control section 20 receives the printing process execution command from operator W as an input therefrom. When the printing process routine is started, CPU 21 of printing control section 20 first executes an abutment process of bringing board S into abutment with screen mask M by causing board processing section 30 to convey, fix, and lift up board S. For this process, CPU 21 causes mask work section 26 to adjust the position of screen mask M for position alignment of the pattern hole with board S. Subsequently, CPU 21 causes cartridge 36 to move to lie above screen mask M, causing cartridge 36 to discharge solder therein onto screen mask M. Subsequently, while causing printing head 23 to move, CPU causes squeegees 25 to lower so as to be brought into abutment with an upper surface of screen mask M while causing these squeegees 25 to move in the front-rear direction so as to print the solder on board S. In this way, printing control section 20 executes the printing process including the board conveyance and fixation process, the solder supply process, and the squeegees moving process to thereby print the solder on board S. In addition, when the use of screen mask M is completed, CPU 21 executes an exchange process of exchanging it with screen mask M for a subsequent use. Firstly, CPU 21 pulls out accommodation rack 80 from the interior portion of the housing of printing device 11 (a third step in Fig. 6), and lifts up accommodation rack 80 to the exchange position (a fourth step in Fig. 6). Then, CPU 21 causes exchange section 27 to exchange screen masks M, and when the exchange is completed, CPU 21 causes rack moving section 43 to move accommodation rack 80 to the accommodation position. CPU 21 repeatedly executes the printing process while exchanging screen masks M until the production process of all types of boards S described in the production plan is completed.
Next, a mounting process will be described in which mounting device 15 mounts component P on board S. When a mounting process is started, CPU 60a of mounting control section 60 firstly causes board processing section 61 to load and fix board S. Subsequently, CPU 60a reads out the mounting condition information, and causes mounting head 66 to pick up component P from feeder F attached to component supply section 63 based on the mounting condition information and to dispose the component P onto board S. When the disposition of component P on board S is completed, CPU 60a causes board processing section 61 to discharge board S and repeats the process described above. During the mounting process, CPU 60a manages the number of consumed components in each feeder F, and when the remaining number of the components becomes equal to or lower than a predetermined warning value, CPU 60a transmits the information to host PC 13a. Host PC 13a causes loader 18 to execute the exchange work based on this instruction list. Loader 18 moves along X-axis rail 19 between storage device 13 and mounting device 15 and executes the exchange process of feeders F in work target mounting device 15.
With printing device 11, when accommodation rack 80 is accommodated in the accommodation position as shown in Fig. 7A, since accommodation rack 80 is accommodated inwards of the front surface of exchange unit 40, traveling path 14 on which automatic conveyance vehicle 16 travels can be widened. In addition, with printing device 11, since accommodation rack 80 is moved to the exchange position only for a temporary period of time during which screen masks M are exchanged as shown in Fig. 7B, a period of time during which the region of traveling path 14 is limited can be shortened.
Here, a correspondence relationship between the elements of the present embodiment and elements of the present disclosure will be clarified. Printing section 22 of the present embodiment corresponds to a printing section, exchange unit 40 corresponds to an exchange unit, mounting device 15 corresponds to a mounting device, loader 18 corresponds to a moving work device, automatic conveyance vehicle 16 corresponds to an automatic conveyance vehicle, and traveling path 14 corresponds to a traveling path. In addition, receiving section 42 corresponds to a receiving section, rack moving section 43 corresponds to a rack moving section, left-hand side unit 41 corresponds to a left-hand side unit, right-hand side unit 51 corresponds to a right-hand side unit, lifting and lowering space 49 corresponds to a lifting and lowering space, and storage device 13 corresponds to a storage device.
Mounting system 10 of the present embodiment described heretofore includes printing device 11 including printing section 22 configured to execute the printing process of printing the viscous fluid on board S, which is the processing target object, using screen mask M, exchange unit 40 disposed in printing device 11 and configured to automatically exchange printing related members for use in printing device 11 between printing device 11 and exchange unit 40, one or more mounting devices 15 including mounting section 64 configured to mount component P on board S, which is the processing target object, and loader 18 as the moving work device configured to move around the circumference of mounting device 15 so as to automatically attach and detach mounting related members for use in mounting device 15 between mounting device 15 and loader 18. In this mounting system 10, printing device 11 and mounting device 15 are disposed such that the front surfaces thereof lie on the same side, and exchange unit 18 and the moving work device are disposed on the same side. With this mounting system 10, since exchange unit 40 of printing device 11 and loader 18 of mounting device 15 are disposed on the same side, the work efficiency in exchanging members and the space efficiency of the work space can be enhanced more. In addition, with mounting system 10, since the front surfaces of printing device 11, storage device 13, and mounting device 15 lie on the same side, and loader 18 and the attachment section of storage device 13, exchange unit 40, operation door 11a of printing device 11, the operation door of mounting device 15, operation panel 38 of printing device 11, operation panel 68 of mounting device 15, and the like are disposed on the front surface side of printing device 11, storage device 13, and mounting device 15, the necessity of operator W and automatic conveyance vehicle 16 moving around to a rear surface side of the devices can be suppressed more, thereby making it possible to enhance the work efficiency of operator W and automatic conveyance vehicle 16 more.
In addition, mounting system 10 includes automatic conveyance vehicle 16 configured to convey printing related members for use in the exchange unit and convey mounting related members for use in loader 18, and automatic conveyance vehicle 16 has traveling path 14 on the side where the exchange unit and the moving work device are disposed. With this mounting system 10, since automatic conveyance vehicle 16 conveys members to be exchanged, the work load of operator W can be reduced. In addition, since automatic conveyance vehicle 16 travels on the same side as exchange unit 40 and loader 18 when automatic conveyance vehicle 16 moves to exchange unit 40 and loader 18, the moving efficiency of automatic conveyance vehicle 16, the efficiency of moving space, the exchange work efficiency, and the like can be enhanced more.
Further, exchange unit 40 includes receiving section 42 configured to receive accommodation rack 80 accommodating printing related members and rack moving section 43 configured to move accommodation rack 80 between the accommodation position where accommodation rack 80 is pulled into the interior portion of the housing of printing device 11 and the exchange position where accommodation rack 80 is made to project from the housing. With this mounting system 10, since exchange unit 40 moves accommodation rack 80 accommodating printing related members altogether, no power source is required in an interior portion of accommodation rack 80, thereby making it possible to make accommodation rack 80 compact in size. In addition, for example, when no exchange is carried out in accommodation rack 80, exchange unit 40 holds accommodation rack 80 in such a state that accommodation rack 80 is pulled into the interior portion of the housing of printing device 11, thereby making it possible to make the housing itself of printing device 11 more compact in size. Then, since printing device 11 can be made compact in size, the efficiency of the work space where to exchange members can also be enhanced more. In addition, exchange unit 40 is formed such that length A in the front-rear direction is shorter than length B of the accommodation rack in the front-rear direction. With this mounting system 10, the size of the device can be made more compact at all times except when exchange unit 40 makes use of accommodation rack 80, as a result of which the efficiency of the work space where to exchange members and the work efficiency then can be enhanced more.
Further, when accommodation rack 80 is situated in the accommodation position, exchange unit 40 accommodates accommodation rack 80 in the same surface as the main body front surface of exchange unit 40 or inwards of the main body front surface, whereas when accommodation rack 80 is situated in the exchange position, exchange unit 40 supports accommodation rack 80 in the position projecting from the main body front surface of exchange unit 40. With this mounting system 10, in particular, when accommodation rack 80 is situated in the accommodation position, the size of the device can be made more compact, as a result of which the efficiency of the work space where to exchange members and the work efficiency then can be enhanced more. In addition, exchange unit 40 includes left-hand side unit 41 disposed on the left-hand side of the housing of printing device 11 and right-hand side unit 51 disposed on the right-hand side of the housing, and has lifting and lowering space 49 where to lift up and lower accommodation rack 80 between left-hand side unit 41 and right-hand side unit 51. With this mounting system, in exchange unit 40, accommodation racks 80 can be exchanged by inserting accommodation rack 80 into lifting and lowering space 49 defined between left-hand side unit 41 and right-hand side unit 51, whereby printing related members are exchanged more easily. In addition, accommodation rack 80 has no power to move printing related members. With this mounting system 10, accommodation rack 80 can be made more compact in size, as a result of which the efficiency of the work space where to exchange printing related members and mounting related members can be enhanced more. Further, mounting system 10 includes storage device 13 for storing mounting related members between printing device 11 and mounting device 15, loader 18 exchanges mounting related members between storage device 13 and mounting device 15, and storage device 13 is disposed such that the exchange work position where to exchange feeders F lies on the same side as exchange unit 40 and loader 18. With this mounting system 10, since in exchanging printing related members and mounting related members, the exchange work can be executed on the same side as these devices, the work efficiency and the work space efficiency in exchanging members can be enhanced more.
Here, mounting system 10 of the present disclosure is not limited to the embodiment described above at all, and hence, needless to say, mounting system 10 can be carried out in various forms without departing from the sprit and scope of the present disclosure.
For example, in the embodiment described above, mounting system 10 includes automatic conveyance vehicle 16 so as to automatically convey printing related members and mounting related members; however, the present disclosure is not particularly limited thereto, and hence, operator W may convey printing related members and mounting related members.
